Prophets

Bukhari :: Book 4 :: Volume 55 :: Hadith 582

Narrated Ibn 'Abbas:

The Prophet said, "May Allah bestow His Mercy on the mother of
Ishmael! Had she not hastened (to fill her water-skin with water
from the Zam-zam well). Zam-zam would have been a stream flowing on
the surface of the earth." Ibn 'Abbas further added, "(The Prophet)
Abraham brought Ishmael and his mother (to Mecca) and she was
suckling Ishmael and she had a water-skin with her.'
